They need to hook up a meter to it and determine if the control board
is really sensing a no-flame condition before it shuts off the gas.
In other words is the flame going out because the gas valve got turned
off or is the flame going out so the control board turns the gas valve
off and starts a relight.

You might take a look a the flame sensor position. It needs to be in
the flame. Closer is not always better, it needs to be in the visible
part of the flame.

I forgot to ask, what pinballs do you have :-) I've got an aces &
kings and a grand prix. I did a full cabinet repaint on both of them
including making stencils. Here's a shot of my grandprix.
